Claims.

This invention relates to new and useful im provements in slide buckles and means for securing slide buckles in place on overall straps and the like.

' 5 An object of the invention is to provide a slide buckle and attaching means therefor so constructed as to be readily applied and removed from a garment or the like, as for example an overall shoulder strap, entirely by hand and without sewing or the use of machinery.

Another object is to provide a means .as stated and which when attached eliminates the necessity for selvage sewing ordinarily required to prevent ravelling.

A further object is to provide a device for the purpose stated and which may be quickly aud easily attached and which will not slip once properly attached.

An additional object is to provide a means for the purpose and having the characteristics stated and which may be made entirely by automatic machinery and therefore be cheaply manufactured and offered for sale.

Other and additional objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing. It is to be understood, however, that the invention is not limited to the details shown and described but comprehends all such variations and modifications as fall within the scope of the appended claims.

1931, Serial No. 512,513

Fig. 10 is a plan view of the frame showing how it may be stamped from sheet metal, and

Fig. 11 is a transverse section thereof.

Referring in detail to the drawing and particularly to Figs. 1 through 6, at 10 is shown the upper or bib portion of a pair of overalls including a shoulder strap 11 usually of denim carrying a loop 12 engaged over a button 13 on the bib. Loop 12 is secured to the strap by passing or threading an end of the strap through the eye 14 of the loop and then securing the end of the strap to a slide buckle 15.

While there is a particular form of slide buckle shown at 15 having substantially square side bars 18, it is to be understood that the form shown need not necessarily be used but that various forms of side bars such as round, rectangular, oval or any of those shown in my Patent No. 1,820,578, dated August 25, 1931 may be used. It may also be stamped from sheet metal as shown in Figs. 10 and 11. Slide buckle 15 is shown as formed from a single length of stock substantially square in cross section but it will be appreciated that the crosssectional configuration of the stock, or whether or not but a single piece of stock is used, is not controlling. Also the round or other sections may be flattened for stamping on the dealers name or some special design.

In the formation of the buckle 15 the stock may be bent upon itself intermediate its ends to 35 form the short parallel portions 16 and then bent to extend in opposite directions for short distances as at 17. Next the stock is again bent substantially at right angles to form the side bars 18 of the loop or buckle and then again at right angles to form the short bars 19 corresponding with the portions 16. The end portions 19 of the stock are then bent into parallel relation to extend as at 20 and are preferably welded together as at 21.

It is not necessary to thread the end of the strap 11 through the slide buckle 15 when positioning the buckle on the strap as in the usual type of buckle. The operation of applying the buckle to the strap may be easily and quickly completed. After placing the buckle against the front of the strap it is merely necessary to slip first one edge of the strap over either the portion 16 or the portion 20 and then to slip the other edge of the strap over the remaining portion, the strap being first doubled inwardly whereby its edges will readily pass over the ends of portions 16 and 20. The buckle will then be positioned as shown in Figs. 1 and 2 with the side bars 18 forwardly of or against the forward o face of the strap and with the portions 16 and 20 against the rear face of the strap.

According to the present invention it is not necessary to sew the free end portion 22 of the strap 11 to the slide buckle 15. Further, it is not necessary to employ selvage stitching to prevent raveling of the end of the strap. It will be understood that ordinarily selvage sewing is necessary to prevent raveling of the end of the strap and it is further usual to bend the end of the strap about a portion of the slide buckle and sew the strap so as to attach it to the slide buckle. These operations are eliminated by the present invention.

One form of means whereby the advantages mentioned in the preceding paragraph result is shown in Figs. 2, 3, 4 and 6 and is generally designated 23. This attaching means 23 may be stamped from sheet metal stock and comprises a body portion 24 the upper edge of which adjacent each of its ends carries attaching means or lugs 25. These lugs 25 should be of relatively easily bendable material whereby they may be bent by hand and whereby they may be repeatedly bent and straightened for the purpose of attaching the free end of the strap to the slide buckle.

Intermediate the lugs 25 the attaching means is bent or folded to substantially U-shape in transverse cross-section. To form this U-shaped portion the material forming the body may be cut or lanced whereby a portion 26 thereof may be bent downwardly to a position parallel with but spaced slightly forwardly of the body portion. The portion 26 is of course secured to the body portion being connected therewith as at 27 and it will be understood that when the attaching member 23 is slipped over the free end of the strap as shown in Figs. 3 and 4 the said free end will be protected and raveling thereof prevented.

Attaching member 23 as before suggested is attached to the end portion 22 of the strap 11 without sewing the same thereto. To this end after the member has been disposed over the end of the strap as shown in Figs. 3 and 4 the assembled arrangement may be operated on by suitable machine whereby to press inwardly the portion 26 to clamp the end of the strap between it and the body portion 24. To more securely hold the strap, lugs or burs 28 may be formed in the bar 26 when blanking out the buckle and at the same time aligned depressions 28' formed in the surface of the body 24. The clamping of the strap will press the lugs 28 of the attaching member into the material of the strap as most clearly shown in Fig. 4 and securely hold it.

In the use of the device after the slide buckle has been positioned on the strap and the attaching member 23 secured to the strap as above described, the loop 12 may have the strap threaded thereto. The next operation is to secure the free end of the strap to the slide 15 and this may be accompilished by passing the lugs 25 up beneath the portions 16 and 20 of the slide buckle and between them and the rear surface of the run of strap 11 so as to dispose the said portions 16 and 20 at the opposite side edges of the portion 26 of the attaching member as indicated in dotted lines Fig. 2. With the parts thus positioned it is but necessary to bend the lugs 25 downwardly about the portions 16 and 20 as clearly shown in full lines Fig. 2. If preferred the clip 23 may be reversed and the lugs 25 wrapped around the stud portions 16 and 20 in the opposite direction and from the back.

It is preferred the free end of the lugs 25 be turned in somewhat at the undersides of the portions 16 and 20 as suggested at 29 in Fig. 2. With the portions 16 and 20 swedged or flattened as above described it will be obvious that a more neat construction is provided since it will be possible to dispose the lugs 25 more within the plane of the loop and thus a relatively flat structure is obtained.

Turning now to the form of the attaching means shown in Figs. 7. 8 and 9 it will be noted that this attaching means is adapted to be applied to the strap entirely by hand and without the use of any type of machine. This attaching means, generally designated 30, may be formed from a single length of material bent upon itself as at 31 to provide forward and rearward bars or portions 32 and 33. As herein shown, the portion 33 adjacent its ends and at its upper edge carries bendable lugs 34 corresponding with the lugs 25 of the attaching means 23 of the first form. Further, the rear member 33 is provided with spaced perforations 35 the purpose of which will later appear.

The front portion or bar 32 is adapted to be bent into parallel relation with the rear portion or bar when applying the attaching means to a strap. Further, the bars 32 and 33 may be pressed or corrugated to form ribs as at 36 to add rigidity to the same. At points spaced apart as are the openings 35 in the bar 33, the bar 32 is lanced to i give the same a substantially V out and the V- shaped pieces are then pressed downwardly to form the spikes 37. It will be obvious that the spikes are to bite into the strap.

The attaching member or means 30 is secured to the end of strap 11 by disposing the bar 33 of the member across the rear side of the strap adjacent the end thereof and by then pressing the bar 32 against the front side of the strap. This will cause the spikes or teeth 37 to dig into the material of the strap as most clearly shown in Fig. 9. Next the extension or end 39 carried by either the front bar 32 or the rear bar 33 is bent about the edge of the strap and against the other bar. In the drawing the extension 39 is shown as carried by the bar 32 and when bent into position is disposed against the rear side of bar 33.

The attaching means 30 operates in the same manner as does the attaching means 23. That is, when the means 30 is used to secure the end of a strap the lugs 34 will be passed up in the rear of the portions 16 and 20 of the slide buckle between them and the rear surface of the run of strap 11, and will then be bent over the forward faces of said portions of the slide buckle. The important distinction between the two forms of attaching means is that while the attaching means 23 is particularly adapted for being applied or secured to the end of the strap by machine, the attaching means 30 is adapted to be secured by hand. From this it will be seen that the means 30 may be readily detached before laundering and the like and that in both forms the slide buckle and loop 12 may also be detached before laundering whereby there will be no occasion for the metal parts rusting or being bent out of shape or broken.

In Figs. 10 and 11 the frame 15 corresponding to frame 15 is shown as stamped from sheet metal. It is used with the run of the web and for attaching the free end thereof the same as frame 15. However, for strengthening so it may be stamped from thinner gauge metal the various bars 18', 19' and 16' may be curved transversely as indicated making them concavo-convex in cross section, or there may be stamped a longitudinal rib in them for strengthening. As indicated above the square bar or wire is shown merely for illustration as other shapes may be used equally as well, such for example as round, flattened, rectangular and similar shapes.

Having thus set forth the nature of my invention, what I claim is:

1. In combination, a slide buckle including bar portions, means secured to the end of a strap, said means including an elongated body member, pliable lugs extending from one longitudinal edge of said body member adjacent its ends, said body member including a flange like portion on said edge between said lugs and bent into substantially parallel relation to the body member and clamping the end of the strap between itself and the body member whereby to secure the body member to the strap, and said pliable lugs folded about said bar portions of the slide buckle and securing the body member and thereby the strap end to the buckle.

2. In combination, a slide buckle including bar portions, means secured to the end of a strap, said means including an elongated body member, pliable lugs extending from one longitudinal edge of said body member adjacent its respective ends, said body member including a flange like portion on said edge between said lugs and bent into substantially parallel relation to the body member and clamping the end of the strap between itself and the body member whereby to secure the body member to the strap, said body member having spaced depressions, said flange like portion carrying spaced burs to bite into the strap and press portions thereof into said depressions, and said pliable lugs folded about the bar portions of the buckle and securing the body member and thereby the strap end to the buckle.

3.
